Testing on a real vehicle – Do you have a VAS5054 adapter available?

To use the demo version with your VAS5054, you first have to connect your smartphone or tablet with the VAS5054.

To do this, go to the settings menu „Interface“ to select the adapter.


Select your desired adapter by clicking it. Then hit “back” and the app will connect to the adapter. This will cause the adapter to be updated, which has no implications for other applications that use this adapter.
